Decision making

Question

How do I make it so that something happens if condition a and condition b are true or condition c and condition d are true. I was thinking something like

if a = true && b = true || c = true && d = true
{
Console.Write("Hello")
}

but I am not sure.

This should do it: if ((a && b) || (c && d)) { Console.Write(Hello); } Don't be afraid to use parentheses if (like me) you can't remember the operator precedence rules. Also no need to do stuff like 'a == true' if 'a' is a boolean expression. Just do 'a'.

Well in that case you wouldn't have been checking whether they were true or not. Unlike some other languages only bool expressions can be true or false in C# and there are no conversions between bool and other types. If say a b c and d were ints and you wanted either a and b to be 1 or c and d to be 1 then you'd do this: if ((a == 1 && b == 1) || (c ==1 && d == 1)) { Console.Write(Hello); }

What if a/b/c/d are not boolean?
